Abstract:
This research is aimed to study the sulfur distribution pattern in each boiling range on various types of crude oil. By classifying crude oil in the study into 3 types by their origins i.e. Middle East, Far East, West Africa and America, we found that the sulfur in various types of crude oil has more tendencies to concentrate in high boiling range such as Gas Oil and Fuel Oil. Thus, the main cost in treating sulfur shall be the desulfurization of such high boiling range fractions, including the blending of Fuel Oil to meet its specified sulfur content. We have carried out the relationship analysis between the sulfur distribution pattern and boiling range of each fraction by using Data Analysis tools Pak under Microsoft Excel® software at 95% confidence level and found that the sulfur distribution pattern in each boiling range of crude oil was significantly represented with the parabolic regression equation. From the above, we can apply the knowledge of sulfur distribution pattern to evaluation of the change in sulfur treating cost when the crude sulfur content deviates from the crude oil database. This can lead to more precise evaluation on crude selection.
